For designing and examining flow of traffic, congestion, and the influence of different aspects on traffic activity, the traffic simulation can be beneficial which is considered as an intriguing project. We instruct you by means of developing a simple traffic simulation in Python through the utilization of a basic framework. Generally, we intend to simulate vehicles that are traveling on a single-lane road, however it is possible for you to prolong this to more complicated simulations:

Step 1: Install Necessary Libraries

We plan to utilize numpy for managing numerical processes and matplotlib for visualization in this simulation. It is advisable to install them with the support of pip, when we don’t have installed these libraries:

pip install numpy matplotlib

Step 2: Set Up the Traffic Simulation

Our team aims to initiate through simulating a basic traffic setting in which cars travel across a single-lane road. By means of basic regulations, we focus on simulating the cars traveling across the road: traveling in forward direction is the main intention of every car, however it should stop or decelerate when some other car is toward the front of it.  

The following is a fundamental instance:

import numpy as np

import matplotlib.pyplot as plt

import matplotlib.animation as animation

# Simulation parameters

road_length = 100          # Length of the road (number of cells)

num_cars = 20              # Number of cars

max_speed = 5              # Maximum speed of the cars (cells per timestep)

prob_slowdown = 0.3        # Probability of a car randomly slowing down

# Initialize road and car positions

road = np.zeros(road_length, dtype=int)

car_positions = np.random.choice(range(road_length), num_cars, replace=False)

car_speeds = np.zeros(num_cars, dtype=int)

# Function to update the positions and speeds of cars

def update_cars(road, car_positions, car_speeds):

new_positions = np.zeros_like(car_positions)

new_speeds = np.zeros_like(car_speeds)

for i in range(num_cars):

# Determine the gap to the next car

next_car_index = (i + 1) % num_cars

gap = (car_positions[next_car_index] – car_positions[i] – 1) % road_length

# Speed up if possible

if car_speeds[i] < max_speed:

car_speeds[i] += 1

# Slow down if necessary to avoid collision

if car_speeds[i] > gap:

car_speeds[i] = gap

# Random slowdown

if np.random.rand() < prob_slowdown:

car_speeds[i] = max(car_speeds[i] – 1, 0)

# Update position

new_positions[i] = (car_positions[i] + car_speeds[i]) % road_length

new_speeds[i] = car_speeds[i]

return new_positions, new_speeds

# Function to plot the road

def plot_road(road, car_positions):

road[:] = 0

road[car_positions] = 1

plt.imshow([road], cmap=’binary’, aspect=’auto’)

plt.title(“Traffic Simulation”)

plt.xlabel(“Road”)

plt.ylabel(“Time Step”)

# Animation function

def animate(i):

global car_positions, car_speeds

car_positions, car_speeds = update_cars(road, car_positions, car_speeds)

plot_road(road, car_positions)

# Set up the animation

fig = plt.figure(figsize=(10, 2))

ani = animation.FuncAnimation(fig, animate, frames=200, interval=100)

plt.show()

Step 3: Run the Simulation

  1. Mainly, the code should be saved as traffic_simulation.py.
  2. Through the utilization of Python, we focus on executing the script:

python traffic_simulation.py

Step 4: Customize and Extend the Simulation

To prolong and adapt the simulation, the following are few effective plans:

  1. Multi-Lane Traffic: For enabling cars to divert lanes to surpass slower cars, we intend to prolong the simulation to numerous lanes.
  2. Traffic Lights: Generally, traffic lights ought to be included at junctions. On flow of traffic, our team simulates their influence.
  3. Variable Speed Limits: Across the road, we plan to apply various speed limits. It is significant to examine in what manner traffic is impacted by them.
  4. Accidents and Roadblocks: Mainly, obstructions or accidents ought to be simulated which generate specific areas of the road to be obstructed. We aim to investigate in what manner traffic trends vary in an efficient manner.
  5. Real-World Data Integration: In order to simulate certain traffic conditions, or to initialize and verify the simulation, it is beneficial to employ actual world traffic data.
  6. Complex Driver Behavior: The more complicated driver activities like secure driving, response times, or high-speed driving have to be initiated.
  7. Pedestrian Crossings: Mainly, pedestrian crossings must be simulated. On flow of traffic, our team plans to examine their influence.
  8. Adaptive Traffic Lights: The traffic lights ought to be executed which varies on the basis of traffic scenarios in a dynamic manner.
  9. Highway Simulation: In order to design highway traffic with off-ramps, on-ramps, and merging lanes, we aim to prolong the simulation.
  10. Interactive Simulation: An interactive version should be developed in such a manner in which users are able to fix speed limits, include obstructions, and park cars in an appropriate manner.

Description of the Code

  • Road and Cars Initialization: First of all, we have to configure a road that can be depicted as a 1D (One Dimensional) array. On the road, cars are parked in a random manner. An initial speed of zero is included in every car.
  • Updating Car Positions: The perception for upgrading position of every car on the basis of its acceleration and the distance to the car towards front are managed through the update_cars function. Whenever probable, cars are able to accelerate to an extreme speed. To prevent collision, it decelerates when required. In order to simulate road situations and human activities, it decelerates randomly in a periodic manner.
  • Visualization: In order to visualize the cars and road, our team aims to employ matplotlib. As a binary image, the road is plotted in which 0 depicts an empty space and 1 depicts a car.
  • Animation: To develop an animation, replot the road and upgrade the positions of the car at every time step through executing the simulation in a loop.
